Multi Family Building Operator Practice Test

Which action is not a part of regular maintenance for an electric water heater?

Perform a carbon monoxide test Check the pressure relief valve Drain and flush the tank Inspect electrical connections

Correct Answer:

Perform a carbon monoxide test

Explanation:

Carbon monoxide testing isn’t part of electric water heater upkeep because CO comes from combustion, and electric units don’t burn fuel. Since there’s no combustion in an electric heater, there’s no CO to test for. The other tasks are standard safety and performance checks: the pressure relief valve should be inspected to ensure it operates and isn’t blocked, preventing dangerous pressure buildup; draining and flushing the tank removes sediment that can reduce efficiency and shorten the tank’s life; and inspecting electrical connections helps catch loose or corroded wiring that could lead to overheating or fire. These steps help keep the heater safe and reliable, which is why they are part of regular maintenance.
